3-3. WATCHDOG TIMER CONFIGURATION
This section describes how to use the Watchdog Timer, including disabled, enabled, and trigger functions.
The AR-B1682 is equipped with a programmable time-out period watchdog timer. You can use your own
program to enable the watchdog timer. Once you have enabled the watchdog timer, the program should
trigger the I/O every time before the timer times out. If your program fails to trigger or disable this timer
before it times out, e.g. because of a system hang-up, it will generate a reset signal to reset the system. The
time-out period can be programmed to be set from 1 to 255 minutes.
